The TSA or US Transportation Security Administration maintains a blog showcasing the most ridiculous items they've confiscated.

These items include throwing stars, cans of propane, a series of loaded guns, narcotics, and a collection of grenades hidden inside a tactical vest.

The TSA was founded on November 19th, 2001 in response to the September 11 terrorist attacks.

Air travel was once a much more relaxed affair. When passengers could simply show up to the airport, buy a ticket and then waltz onto the plane. Back then, airport security had a somewhat lackadaisical feel. Passengers were able to carry materials and items on planes that, in retrospect, seem shocking. A 2002 report by CBS News details that baseball bats, darts, knitting needles, pocket utility knifes less than four inches long and scissors were all allowed on airplanes.

These days, the TSA and their security checkpoints are ubiquitous at airports around the US. But there are still the daring and the unaware amongst us that try to sneak items past TSA screeners.

In fact, the agency even documents all of the crazy and absurd items passengers have attempted to smuggle on board airplanes in an interesting and informative blog. Here's a look at some of the weird things people trying to sneak past the TSA:

1. A model of an improvised explosive device or IED

2. Throwing stars and various shivs

3. Knuckle knives

4. Cane swords

5. Machetes

6. Shoe knives

7. A fully-fueled chainsaw in checked luggage

According to the TSA, chainsaws are never allowed on board as carry-ons but may be transported in checked luggage if it has been purged of all fuel and fuel residue or vapors. Some airlines will only transport engine-powered equipment if it has never contained fuel.
